hello, the crash is caused by the Belgium eID MiddleWare by Belgian Government running on your system. do you need that software? if not please uninstall it or else contact its support to see if an update is available or if they can address the issue otherwise: http://eid.belgium.be/en/using_your_eid/need_help/

I took a lunch break in the middle of writing this, and I see you have now fixed it. I was unsure if you may have already updated the software, it has been suggested a few times. It would probably be a good idea to learn how to use Firefox's Safe Mode, it is very useful in troubleshooting and fixing problems.

Sorry, my last answer point 4 was not the best idea because it leaves you with the extension causing a startup crash.

I guess I was hoping you would find one of the other methods would work. Then if necessary the reset option could have been employed, but that needs Firefox to at least give you that option. I am still not sure why you seem unable to start in Firefox's Safe Mode

By far the easiest thing is normally to try to follow the safe-mode instructions. i.e. hold the shift key down whilst using the mouse to click/doubleclick the Firefox icon.

If you are still unable to start in safemode, then to start without the extension do one of these.

Rename the extensions folder. That should effectively remove all or most of your extensions. That involves you finding the profile (much easier with Firefox running) then looking inside it for a folder named extensions. Rename it to oldextensions See

You will be asked for a name for the profile, I suggest you use New01Do not try renaming or deleting profiles, it is far too easy to destroy information,even none Firefox files. (Just delete unused shortcuts)
